Description The Washington State Departments of Ecology and Health jointly investigated the nature and extent of uranium contamination in the irrigation outfalls to the Columbia River. Uranium was found at elevated levels in all of the outfall samples. Analysis of river water after each outfall does not indicate a significant increase in the uranium levels in the river from irrigation water. The ratio of isotopes of uranium found indicates it is of natural origin, and not the result of human activity.
